Android - Unable to select SDK Root folder

Hello,

This is my first Unity Question, so excuse me if I am doing something wrong. I have been having a problem, recently, building to Android. Once I press “Build to Android”, I get a window asking me to “Select Android SDK Root Folder” - I select the folder where the SDK Is stored. Once I hit “Choose”, the window closes, then pops up once more asking the same thing. There have been other threads about this, but no answers. Can anyone help?

Regards,
Keyed.

Is anyone available to help?

first I want to ask you about your unity series (I don’t know how to call it) but, I’m using unity 2017.3.1f1,

second. maybe you should update your Android SDK from SDK manager. But, you must to install the android studio on your laptop first to update the Android SDK
